as in their closing position to'present the `final carded.

In accordance with the present invention` the shaping mould consists of Jfour jaws arranged in pairs pressed vtowards one'another and moving in directionsintersecting at right angles theifacing portions of which correspond to the inal forni of 'the bunch and the sliding ,surfacesV coming into contact are shaped to correspond with this profile. e f

In other wo-rds the bunch passes lintofa pocket or chamber which is then closed on'all sides and the walls of which are shaped throughout to the final form ofthe bunch so that by bringing together the main jaws thev` bunch is transformed positivelyinto its final form without any portions of' the bunch being squeezed out laterally. n l

In order that the bunch can first `be intro-` duced into the mould which is closed before the main pressing jaws are brought together one pair of the jaws is carried by swinging` arms, in order after-theyare moved into `t ie open position to provide space 'or the'inser-y tion of the pre-formed bunch. 1

m lhere are provided two horizontally relatively movable main pressing jaws and two auxiliary pressing jaws movable about horizontal axes and a support in'such manner that with the main jaws and the auxiliary jaws open the bunch introduced between the main pressing jaws rests on thesupport whereupon the auxiliaryy pressing jaws move into operative position and thereby form a closed chambergthe walls of which'exactly tit the final forni of the bunch. j

The invention is illustrated in the accom-- panying drawings in which F ig. 1 is a vertical longitudinal section through the device with the means for operating its parts in the position in which the completed bunch is removed from'the shaping mould Y Fig. 2 shows also in vertical longitudinal r section the apparatus in the position in which a lnew ybunch is introduced, the operating means being omitted, I

Fig. 3 shows the apparatus also in vertical longitudinal section in the position in which the shaping mould is closed after the intro` duction of thenew bunch, Y Fig. 4 shows in vertical longitudinal section the device in the position in which the bunch is pressed, l

Fig. 5 shows the finished bunch as it is removed from the open shaping mould,

Fig. 6 iinally shows in perspective the four jaws of :the shaping press in open position, while Figs. 7 to 11 Ashow further niodiications.

The two main Ashaping' jaws 1 and 2, the recesses 1f and 2 in which correspond to the bunch shown in Figz, are mounted on slides 3 and 4 and are arranged to move longitudi nally in guides 5 and 6. To these slides are connected longitudinally movable rods 7 and 8y which are rotatably mounted on the levers i 9. The levers 9 are movable about the pivots cured to the guide 6. y The auxiliary shaping awsra're provided with pinions 14 and 15 which mesh with one another. rEhe toothed segment 19 secured to the lever 18 meshes with the lower pinion 15. This lever turns aboutthe pivot QOand co-operates by kmeans of its roller 21vwith the 4cam discQQ mounted on the shaft 12. ,In the guide vis arranged alsoA a longitudinally movable support V23',

A26 mounted on the shaft 25.

the forwards-nd 23 of which is provided with two tines. At its rear end the support is attached by means of a link 24 with a lever There is also rigidly mounted on the shaft a forked 0'ripper 27a'nd a pinion 28 which meshes with the toothed segment 30 on the lever 29. The lever y29 turns about they pivot 31 and co-operstes by means of a roller 32 with the cam disc 33. The levers 9j 18 and 29 are pulled by means of suitablesprings 9', 187 and 29 into operative position i. e. against the corresponding cam track.

The operation of the apparatus is as follows:

After the complete bunch has been removed from the open device the support 23 is movedforward and thepre-formed bunch VW is laid on this (Fig. 2) by known means.

' face of the bunch at their meeting point.

fjaws return to Vtheir initial position.

After pressure has been applied to' the bunch-for the proper time the two auxiliary Y The toothed segment 30 controlledby the cam disc 33 now turns the two levers 26 and 27 so that while the support 23 returns to the position shown in- Fig. 1 the forked grippermoves between the recesses 1 and 2 provided on the main shaping jaws 1 and 2 (see Fig. 6)

and holds the bunch in the middle position while the two main pressing jaws 1 and 2 return to their initial position. Then the forked gripper 27 moves into the position shown in dotted lines in Fig. 1 and lays thc bunch on a prismatic support 34 which feeds the same to the devices intended for further treatment of the bunch. Y

In the embodiment shown in Fig. 7 the two main pressing jaws 1 and are-mounted on two rock levers 85 and 36 whichpivot 'about a common pivot 37. YThese rocking levers are comparatively' long soV thatthe movement ofthe two shaping jaws will be practically rectilinear. The rock levers are provided with rollers and 36 whichcooperate with cam discs 88 `and 39 mounted on shafts 4() and 41.- The springs 42 and' 46 engaging the rock levers pullithemalways into operative position. On theshaft 41-is also mounted a cam disc V44 with Vwhich the roller 45 `Onthe double-armed lever 46 co operates. I y vided with a V'tootl'ieol segment`47 Awhich The `'double-armed lever is pro5 l l l l meshes with the pinion 49 mounted on the spindle 48. The pinion 49 which is rigidly connected withthe auxiliary jaw 50 meshes with the pinion 52 mounted on the spindle 5,1 which is rigidly connected with the jaw 53. i* The double armed lever 46 is continu-- ouslypulled against the cam 44 by the springl 54. Onthe shaft 40 is also mounted the cam disc 55 which co-operates with the roller 5i. on the bell crank'lever 57. The support 58 is movable on the guide 59 and is connected by the link 6() with the double-armed lever 57. There is also connected with the doublearmed lever 57 lthe forked gripper 61 which. is identical with the gripper 27 shown in Figs. 1 to 6. The spring 61 tends to press the roller 56 against the cam surface 55.

The modus operandi of this apparatus Jis exactly the same as that described with reference to Figs. 1 to 6. j

Figs. 8 and 9 show a modified construction in two positions invwhichthe su port 62 also replaces the lower auxiliary siaping jaw.l This support is operated in known manner through a link 63 by means of a bell crank lever-'64 one arm 64 of which is also formed as a forkedgripper. In order to prevent separation ofthe auxiliary shaping jaws during the pressingoperation there is screwed on the guide 65 of the main shaping jaw 2 a locking plate i66 behind which the support 62 is disposedwhen in operative position` (as shown in Fig. 9) The locking member 67 for the auxiliary shaping jaw 14 which is operated in known manner by means of a toothed segment c-o-opemting with the pinion 14 j is mounted on theV main shaping aw 1. The support 62 must, of course, be provided with recesses for thepassage of the forked gripper.

In the embodiment shown in Figs. 10 and 11 the lower shaping jaw' 68 is mounted on a bell crank lever 70 operated by the cam disc 69. The bell crank lever turns about the pivot 7l and is drawn by meansof the springl 72' into engaging position with the cam 69. Although the -main shaping jaw 1 is provided with a. locking member 67 forthe auxiliary shaping jaw 14 in this construction a projection for the auxiliary shapingY aw 68 is not necessary with this construction as the line of pressure liesin the direction of the pivot 71.

It should `be mentioned that the forked gripperr64 is rigidly connected with a pin ion` 7 3 mounted on the spindle 74 and the pinion 73 is driven in any suitable manner t not shown) from the shaft 75 by means of a cam disc. y
